(Granted under the provision of sec. 14, act of March 2, 1927; 357 0. G.

In my prior patent application No. 635,272 I have described a method andmeans for producing printed forms on the back of which at definiteplaces carbon sheets are gummed for 5 the purpose of manifolding. Theinvention of the said prior patent application includes arrangements forautomatically feeding the forms as also for printing and gumming thesheets with adhesive but only at the points where the carbon sheets areto be applied.

The present invention is an improvement in or modification of theinvention of the said prior patent application as regards the supply ofthe carbon sheets and is distinguished principally by the provision ofmeans for severing and applying the carbon sheets, a feeding device anda removing device, these devices being preferably provided on a singlemachine but being provided as independent machines if desired.

The improved means are illustrated in the accompanying drawing in whichFig. 1 shows diagrammatically in side elevation the severing andapplying apparatus. Fig. 2 shows the same arrangement in plan view. Fig.3 shows the slots 25 in the lifting magazine and in the pressingapparatus.

In the embodiment shown in Fig. 1 the magazine is supplied in knownmanner from a spool of carbon paper which is unwound at intervals isalso previously printed and provided with adhesive). The carbon paper iscut into small sheets corresponding to the points at which they are tobe gummed to the form.

35 During the intervals of movement of the form blocks and 25a aresecured is raised in the direction of the arrow 7 being guided by afixed plate 23. The blocks 25, 25a are provided with one or morepassages which lead to the collecting chambers 27, 27a. The latter areconnected by a flexible hose or tube with an air pump of known kindwhich operates in such manner that suction action is exerted only on theupward movement according to Fig. 3 and the pressure action is exertedat the moment of pressing and of the downward movement indicated by thearrow i The waste portions of the carbon paper not utilized are removedat the outlet side of the machine by rollers.

Fig. 2 shows by way of example the direction of movement of the form 9and beneath it and transversely thereof the direction of movement of thecarbon paper 20.

apart and entrained (with the paper sheet which and of the carbon papera plate 26 on which Naturally the path of the carbon paper might bedisposed over the path of the form, the device being reversed. Also thecarbon paper and forms might move parallel toone another in the samedirection or in opposite directions.

The carbon paper may be replaced byone or more narrow sheets of carbonpaper each with a variable feeding device. In the apparatus shown by wayof example in Fig. 3 a slide' 28 slides in guides 31 which are providedwith suction faces which are connected by flexible tubes to areciprocating air pump. The slide 28 which is operated mechanically ismoved over the magazines 12, 13 which are secured to the plate 10. Thelatter is raised in the direction of the arrow P so that the suctionfaces 30 slightly enter the magazines 12, 13. The pump operates in suchmanner that at a suitable point of time it exerts a suction action onthe previously cut carbon sheets which then adhere to the suction faces.The plate 10 then moves down as shown by the arrow f The slide isdisplaced in the direction of the arrow 12 and remains above the printedform coated with gum. a

The plate 29 with the heads 8 rises in the di- 25 rection of the arrow 1and presses against the paper 9 and against the suction faces 30, whichhold the carbon sheets so that they may be gummed. The pump now exerts apressure action. The slide 28 moves back in order to re- 30 ceivefurther carbon sheets while the form is again pressed, provided withadhesive and fed forward again.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

1. In an apparatus for arfixing carbon paper sheets to selectivelygummed forms and the like, means for severing and applying carbon sheetsto the forms comprising an intermittently driven spool, a matrix, diesco-operating with said matrix to cut the carbon sheets of the desiredshape during the intervals of the feeding ,movement, and suction meansadapted to cause adherence of the carbon sheets to the dies, wherebysaid out sheets are pressed by the dies against the previously gummedforms to cause adherence thereto after the suction means have beenrendered inactive.

2. In an apparatus as claimed in claim 1, a plurality of spools, andmeans to individually actuate these spools, the carbon paper being inthe form of narrow strips wound over said spools.
